Hot air station warms up but bails out halfways (Atten ST-862D rebadge)
<< < (2/2)
BlownUpCapacitor:
If I recall correctly, there is a reed switch in the heat gun that turns off the heater when in the holder. That reed switch may be faulty. Check that.

It seems like it is definitely the reed switch.
When I hold the handle very horizontal, it works.
Only at an angle is the issue.

Is the reed switch at the socket end somewhere?

you must have a sensor in your handle, tc or ntc/ptc or whatever, he can give the same issue (well, him&his harness).
reed activating only horizontal without some external magnetic stimulus is very odd imho. my primary suspect is the temp sensor or around him

It is perfectly stable in temperature when the handle is fully vertical or horizontal, not at an angle.
perieanuo:
so measure at the end of the harness on main pcb-side, you'll get if heating is powered and if temp feedback is ok. then you know where to look
